We're not talking about Fuji-like orbs are we? I thought this "orb" was the extra reflections that appear in bright specular regions which incidentally I'm seeing quite often on the television these days.

I don't think these are Fuji's White Orbs, because they are continuous white blobs not patterned, and probably result from sensor bleeding, taking place in the sensor.

These appear to be patterned flares, likely resulting from a reflection from an intense beam from the sensor, acting as a diffraction grating, back to the lens, and in turn back to the sensor from one of the lens element surfaces. Similar to known patterned flare issues with for instance the RX-100, E-PL2, Sigma DP, and the purple flare of the Panny 7-14mm lens on Oly cameras.
